LD Celulose, a joint venture between Austrian Lenzing and Brazilian Dexco (earlier Duratex), invested around USD 1.38 billion in a new greenfield dissolving pulp mill. It has a production capacity of 500 thousand tonnes of dissolving wood pulp per year, in addition to 144 MW of clean energy. The mill is designed to be very energy efficient and will deliver more than 50 percent of the electricity it generates to the public grid as renewable energy. The special pulp fibers produced at LD are used in the textile industry, generating innovative, sustainable and high-tech fabrics.
Valmet proved to be a partner with flexibility to meet demands and achieve the expected results.
